Terracotta Panel Curtain Wall System

Definition
Terracotta panels are manufactured through vacuum high-pressure extrusion and high-temperature firing of natural clay. As an innovative architectural cladding material, terracotta curtain wall systems deliver a dignified and expressive aesthetic, exceptional durability, and a distinctive character that enhances in appearance over time. Based on technical research and construction experience, our company has developed an integrated construction methodology for terracotta curtain walls with horizontal framing. Terracotta is an environmentally sustainable material requiring no maintenance, growing more visually compelling with age. The open-jointed, dry-mounted terracotta facade system functions as a breathable enclosure, allowing straightforward installation and individual panel replacement. Its unique advantages—low energy consumption, eco-friendliness, energy efficiency, longevity, self-cleaning properties, consistent colouring, and refined elegance—enable superior decorative performance. It harmonizes advanced technology with ecological principles, offering high value and cost competitiveness compared to glass, metal, and stone curtain walls.

Features

• Simple construction process with easy replacement (see Figure 2.1) and controllable quality

• Low energy consumption and construction costs with high cost-effectiveness

• Structurally stable, minimal hidden risks, and free from common quality defects

Replacement
Rapid installation, high precision, and simplified on-site assembly are achieved. The panels can be cut as needed, and dedicated profiles are available for corners and complex junctions, reducing labour intensity. No heavy lifting is required, saving both manpower and material resources.

Thermal and Environmental Performance
The system provides significant thermal insulation and energy conservation, along with exterior protection (as illustrated in Figure 2.1-1). A ventilated air cavity behind the panels reduces heat transfer, dissipates moisture and heat, prevents condensation in the backing cavity, and improves occupant comfort. This multi-dimensional insulation meets the requirements of GB 50189-2005 "Design Standard for Energy Efficiency of Public Buildings".

Structural Performance
The installed system exhibits high rigidity, strong corrosion resistance, high impact resistance, and light self-weight. It is suitable for buildings in high wind-load regions and seismic zones, with seismic fortification intensity up to degree 10 (basic seismic acceleration 0.2g, Site Class II).

Water Management
This methodology effectively manages rainwater and snowmelt runoff after construction, overcoming limitations in fully sealed or stored drainage approaches used in conventional curtain walls. Using equal-pressure principles, it redirects water away from the building surface, preventing infiltration and erosion of the structural support.

Technical Principle
The terracotta panel curtain wall with horizontal rails is a unitized system. Vertical mullions and horizontal rails are anchored to the primary structure, forming a support framework. Terracotta panels are mechanically fixed to the rails using specialised brackets, resulting in a high-performance architectural finish.
